2. Select "Troubleshooting" from the menu
3. Select the "Rescue" option from the menu
4. Select "Continue" from the menu, this will mount the os to /mnt/sysimage
5. Depending on what distro you are running you need to edit one of these files:
/mnt/sysimage/boot/grub/menu.lst /boot/grub/menu.lst /etc/grub.conf /boot/grub/grub.conf

vi menu.lst
7. Completely remove the line that starts with "Password", you can do this by moving to the line and pressing "dd"
